BEM-T Types

Features of BEM-T Types

These are compact power supplies for controlling spring-actuated brakes with rated voltages of 45 V DC/90 V DC/180 V DC. They are compatible with input voltages of 100 V AC, 200 V AC, or 400 V AC.The direct current required to operate spring-actuated brakes can be obtained simply by connecting/inputting. These are ultra-compact, slim power supplies that can be installed anywhere. The mountings are also movable, so the input/output direction can be set freely. Also, since the entire case is molded of resin, they can be used in adverse environments and atmospheres, such as dusty locations.

BEM-2T/4T types take a commercial power supply as the input and generate a half-wave rectified DC voltage on the output side. These power supply devices are known for their very simple construction, compact size, and low cost, but their voltage pulse is large. They are therefore prone to generating variations in operating response in electromagnetic clutches and brakes, they produce a howling noise when conducting, and they tend to generate more heat from their electromagnetic coils than full-wave rectified supplies or smoothing supplies.
When the above are to be avoided, consider changing to a full-wave rectified supply (BEM-2F types), smoothing supply, or a DC 24 V specification.
[How to Calculate Output Voltage]
Output voltage = Input voltage × a (a set coefficient)
* a (set coefficient) = 0.45: half-wave rectification
(Ex.)
BEM-2T: AC200V × 0.45 = DC90V
Note that when the rated voltage of the electromagnetic coil does not match the output voltage calculated above, you will not be able to obtain the electromagnetic clutch/brake characteristics given in the specifications.
